Our 12th grade son is about halfway through this course. It is clearly written with no errors that we have been able to find in the answer key so far. As with all Lifepac math courses, self tests are included in each Lifepac. The difference is that they are much more frequent (about 8 self tests per Lifepac, vs. the 3 to 4 each that we have seen in all Alpha Omega math courses prior to grade 12), which makes sense given the more challenging subject matter. I am looking forward to using this course again in a few years with our now-9th grader.

I have been a huge fan of Alpha Omega products for the past 10 years, but please don't purchase the 12 grade mathematics Lifepacs for your child. There are many errors that will add to your child's (and your!) confusion in this already difficult subject. These are real math errors - one page has an example showing an obvious error: 45+55=105. I hope that the mom who wrote the other review will see this - the problem may have not been her child's, but was probably due to AOP's careless presentation!

Not for the squeamish! I am sure the curriculum is well- written, but even with three years of self-taught college prep math behind her, my daughter was not able to grasp these concepts on her own. If you are using this curriculum to home school your child, she will need to be highly motivated to complete the course without a tutor.
